Patients with hyperflexion/hyperabduction injury to the glenohumeral joint are at risk for isolated greater tuberosity fractures, which are often undiagnosed or misdiagnosed. In this case report, we describe the clinical decision-making process that led to the diagnosis of an isolated greater tuberosity fracture and subsequent rotator cuff tear.

  • fixation and/or the excision of bony fragments. The closest type of fracture to a greater tuberosity fracture that is described in the literature is an isolated lesser tuberosity fracture. These types of fractures are also very rare and usually occur in association with posterior shoulder dislocation or in conjunction with a comminuted proximal humeral fracture.15 According to Ogawa et al38 in 1997, there were only 60 published cases of isolated lesser tuber- osity fractures. They reported on 10 lesser tuberosity fractures of their own and the previously reported 60 cases. These cases consisted of 52 acute cases and 18 chronic cases. The prevalence of chronic cases illus- trates the fact that lesser tuberosity fractures often are misdiagnosed or completely missed at the time of injury. This is also likely true with greater tuberosity fractures. In addition, it is important when diagnos- ing either greater or lesser tuberosity fractures to distinguish the fracture from a rupture of the corre- FIGURE 1.

No fracture sponding musculature.17 Both rotator cuff tears and identified. fractures can produce similar complaints of pain and weakness in abduction,41,51 making it difficult to distinguish these injuries based on history and physi- cal examination alone. Ogawa et al39 reported in 2003 that isolated greater tuberosity fractures con- tinue to be easily overlooked. They found that 59% (58/99) of patients with shoulder pathology seen in their clinic for second opinions had been misdiag- nosed by outside facilities and did have a greater tuberosity fracture. The purpose of this case report is to demonstrate the need for sound physical therapy clinical decision making in collaboration with the referring physician when treating a patient with an injury for which management and prognosis is not definitively estab- lished. CASE DESCRIPTION The patient was a 45-year-old, right-hand–dominant male who fell on his right shoulder while downhill skiing with his family (February 16, 2003), with a resultant hyperflexion injury. Initially he had some diffuse anterior shoulder pain. Over the course of a few days his pain got much worse and he noted that he was unable to raise his arm over his head. He was referred to physical therapy 16 days postinjury by an FIGURE 2. Initial radiograph, y-view of the scapula.

Ogawa et al38 reported that 3 out of 5 of 52 lesser-tuberosity cases that were treated acutely with open reduction internal fixation had excellent out- comes; yet there are no randomized controlled stud- ies to determine if patients would do just as well without surgical intervention. In the management of patients with chronic greater tuberosity fractures it has been reported that the first choice of interven- tion is conservative treatment, focusing on strength- ening the rotator cuff musculature while protecting the fracture site.38 Given the lack of literature dealing with conserva- tive management of greater tuberosity fractures and the diagnosis of a nondisplaced greater tuberosity fracture, the treating physical therapist, in collabora- tion with the orthopedic surgeon, agreed to manage this patient’s case similarly to that of a patient with a chronic rotator cuff tear/impingement.

An auditor y and visual pleted that showed high T2 signal intensity in the biofeedback unit (Prometheus Group, Dover, NH) was used for 3 weeks (weeks 13 through 15). Biofeedback electrodes were placed on both his anterior and middle deltoid while he performed 2 to 3 sets of 10 repetitions of shoulder flexion and abduction in the plane of the scapula to assist him in reducing recruitment of the deltoid with these mo- tions.

  • Postsurgical Intervention The patient began pendulums and PROM exercises on postoperative day 1. During the first 5 postopera- tive weeks, PROM (flexion, abduction, extension, and internal and external rotation at multiple angles of CASE abduction) in available pain-free ROM was either conducted by a physical therapist or the patient’s wife, who was instructed how to perform PROM properly. Patient-performed ROM exercises were dis- REPORT couraged because EMG studies have shown that the rotator cuff is active with self-assisted ROM.13 He started an AAROM program during his fifth postop- erative week. These exercises were introduced to increase muscle activity and assist in restoring normal patterns of muscle contraction. His exercises for AAROM were performed with a cane for supine FIGURE 5. 3-D reconstructed CT scan 5 months postinjury.
